Answer:

The placebo effect

Explanation:

The placebo effect in psychology refers to a situation in which participants in a research receive beneficial effects due to the administration of an inactive substance or a sham treatment. The positive beneficial effect received can then be attributed purely to believe and not to the treatment itself. A placebo treatment could produce a real healing effect like a true medical or psychological treatment.

The participants who received the sugar believed it to be a memory enhancing treatment hence the slight increase in memory capacity due to placebo effect.

Borders are still guarded zealously and fought for - via wars when required and when not required in equal measure. I see nations fighting
 over water  that preciously scarce resource of the future. I see that terrorists still abound - the Osama Bin Laden types still roam the Earth terrorizing countries and peoples with newer weapons and newer methods of instilling terror. I see that the United States is no longer the sole superpower of the world -- the most powerful country on Earth. I see the most powerful countries dominating the world as being China, India, Brazil and Russia in that order. I see that China and India have become the equivalent of the US and the erstwhile Soviet Union - fighting another Cold War between them and competing for resources and influence around the world.
